In Agrabah one of the bosses in Castle Oblivion is the Genie Jafar.

You will be on three platforms. As you play, the height of each platform will change without warning.

When Jafar throws a fireball at you, if the platform nearest to him or in the middle is raised up higher than the one farther away from him, get on the lower one.
If all platforms are the same height, then go up to the top of the platform. When he throws it at you move to the lower part of the platform.

Every time you try to hit Jafar he will gaurd it and it will cause no damage.
To cause damage, attack him when he raises up to attack you.

A parrot will be flying overhead holding the lamp. If you hit him enough times he will drop a card.

Jafar's remaining HP can be found in the upper right corner.
